- Antivirus is a kind of software used to prevent, scan, detect and delete viruses from a computer. Once installed, most antivirus software runs automatically in the background to provide real-time protection against virus attacks.Comprehensive virus protection programs help protect your files and hardware from malware such as worms, Trojan horses and spyware, and may also offer additional protection such as customizable firewalls and website blocking. On same background explain how does an Antivirus system in a computer function.arrow_forwardA computer virus is a little piece of software that travels from one computer to another and causes problems with its functioning. A computer virus may damage or remove data on a computer, distribute the virus to other computers through email, or even wipe the hard drive clean. Computer infections are often propagated via email attachments or instant messaging conversations. As a result, you should never open an email attachment unless you know who sent it or unless you are expecting it. Viruses might be camouflaged as comical photos, greeting cards, or audio and video files in email attachments. Computer viruses may also be propagated through Internet downloads. They may be found in pirated software, as well as other files and applications that you may download. Why would designers place software inside the kernel (or make use of kernel software) if it is so dangerous? What additional strategies do you use to avoid viruses if you were an antivirus creator or maker?arrow_forwardComputer viruses are malicious software programs that may erase data or wreak havoc on a computer's processing and memory components and are notoriously difficult to detect.

- Intellectual property is a controversial subject in some circles. Considering the amount of effort needed to produce a creative work, such as a movie or a book, and the ease with which digital media allow such things to be duplicated and transmitted for little to practically no cost, an entire industry has been built up around copy protection. One copy piece of copy protection software interfered with the functioning of a computer’s CD/DVD writer, slowing it down significantly and in many cases preventing it from working. The copy protection software producer felt that the measure was justified, claiming that DVD writers were only used to produce illegal copies of commercial works.

This includes not only government but also journalists, publications, and human rights groups. Google's parent Alphabet has stepped up to help with thwarting DDoS against these groups. Since 2016 Project Shield has thwarted DDoS attacks against hundreds of websites in over 80 countries. These attacks were directed at websites in order to silence important information. Project Shield was offered for free to journalists, small publications, human rights groups, and others. But Google is doing that from its own initiative at a relatively high cost. Should there instead be a tax on computer hardware and/or software that goes towards a fund that is then used for organizations like this to have permanent DDOS mitigation?arrow_forward
